Abstract

A group of uv-sensitive heterocyclic compounds characterized as isoxazolin-5-ones were found in some legume seedlings. Their isolation, purification and structural identification are explained. With emphasis on the particular properties of the natural products — chemical and photochemical degradation — the chemistry of N-substituted isoxazolin-5-ones is reviewed. The second part of this paper deals with the distribution, metabolism and with some biological aspects of the title compounds. Their possible origin and function are discussed.
